View Full Version : Is this enough to run my 225 arc welder?

I have a 225/125 Lincoln AC/DC Arc welder and wanted to run it from a dryer outlet. The outlet has 10-2 wire running to a 30a double bar breaker. Is this enough to be able to run the welder safely?
Also, does a 30a double bar breaker = to a 60a single breaker?

I'll be the first to stick my neck out a bit and take a whack from some of the guys here. :eek:
First off, a double 30 off 230v is equal in power (wattage) to 60 amps off a single leg of 120v but that's as far as you want to go with any correlations. The connection types aren't interchangeable.
It's been years but I think lincoln calls for number 10's on that welder, but they also want a 40 or 50 amp breaker. The double 30 isn't the most desirable set up but I'm sure most of your welding will be done in the 70 to 130 amp output range and the 30 amp breaker should handle that just fine while you're working on a more permanent and dedicated circuit for the welder. Do not modify the dryers set-up, build yourself a combo cord/adapter. Later when you get your dedicated welder hook-up you can change the one end of the cord to a 6-50 for the standard welder connection.

Thanks, I'm new to the whole house wiring, breaker set-ups. Never really thought about it until now that I need something done. I'm doing some research on it now and hopefully not ask anymore ignorant questions. Thanks
